Drs1685 Posted July 18, 2015 Share Posted July 18, 2015 So I just came across this, thought I'd share, it was a Chinese site so I couldn't read into the readings, I wonder what the 30cm 45cm and 60 cm are, length above water line maybe Link to comment
bpounds1991 Posted July 18, 2015 Share Posted July 18, 2015 It could very well be from the light itself, I know when I spoke with AI they informed me that the charts on their site are based on being away from the light itself, not underwater. Link to comment
jedimasterben Posted July 19, 2015 Share Posted July 19, 2015 Distance is from the light to the measurement point. Link to comment
evilc66 Posted July 20, 2015 Share Posted July 20, 2015 1023world is a Japanese site btw, and is a pretty big retailer on that side of the world. They do a lot of comparisons of LED lighting. I'm a little concerned that the PAR values are actually a little low. I don't see any evidence of the PAR numbers being broken down into their constituent wavelengths so that the appropriate correction can be added before the totals are added together to get the final PAR number.
